The mattress firmness scale developed by Americans is decidedly more
accessible to customers. This
mattress firmness scale has up to 10 levels. These are adapted to
sleeping positions, but in principle, one is most suitable for most people. This is evidenced by
hotel tests conducted by one of the companies.
In principle, people who
sleep on their stomachs should choose medium-firm mattresses with a firmness of about
6.5/10 according to this scale. However, there is also a very
narrow group of people who sleep on their stomachs but are simultaneously
slim, young, and athletic, which allows them to regenerate faster. For these, a firmness of
above 7/10 may prove to be more beneficial.
For those who
sleep on their side, mattresses with a firmness ranging from
4/10 to 7/10 are recommended, thus medium-firm. Meanwhile, for those who
sleep on their backs, mattresses with a firmness of about
5/10 to 7/10 are also considered medium-firm. This allows for maintaining
spinal support while also providing mattress users with the
great comfort they expect during sleep.
For years, some
American startups have been researching the existence of the ideal mattress firmness that meets the
needs and complaints reported by consumers. To answer the question of
how to choose a mattress that would be ideal for everyone, a comprehensive
hotel test was conducted to provide an answer. Good hotels, wanting to minimize the risk of
guest dissatisfaction with sleep quality, often opt for
universal, comfortable, and durable solutions to avoid complaints. In hotels, guests do not have the option to
determine themselves which mattress they want to choose.
Conclusions from the
hotel tests already conducted leave no doubt that the best mattress firmness for humans is between
6/10 and 7/10, providing both support and comfort. This is also confirmed by tests based on the
pressure point map, ensuring the solutions we use at ONSEN®. Our functional
Osaka Air mattress has precisely this firmness.
